<span>5x-20=2(3x-10)=6x-20, eqivalent to 5x-20=6x-20, it s a contradicion; a 2. 4x - 16 - 2x = 2(x - 8), for this 4x - 16 - 2x =4x-2x-16=2x-16, and 2(x-8)=2x-16, so 4x - 16 - 2x = 2(x - 8) is a identity 3. For the case of 6x - 15 = 3(2x - 6)=6x-16, we have 6x - 15 = 6x-16 it is contradiction 4. 5x - 3(x - 4) = 2(x - 6), we know that 5x - 3(x - 4) =5x -3x+12=2x+12, and 2(x-6)=2x-12, so we have 2x+12=2x-12. That is also a cotradiction, finally we have 1.B, 2.A, 3.B, 4.B</span>

<h3>Answer:</h3>

x=30

<h3>Solution:</h3>
  • First, use the distributive property:
  • 8x-3(2x-4)=3(x-6)
  • 8x-6x+12=3x-18
  • Simplify:
  • 2x+12=3x-18
  • 2x-3x=-12-18
  • -x=-30
  • x=30

Hope it helps.

Answer:

x= ± 3\sqrt{2} /2 +2

Step-by-step explanation:

Use the formula ( b/2) ^2 in order to create a new term. Solve for x by using this term to complete the square.

x= ± 3\sqrt{2} /2 +2

Marcus made a mistake in Step 2. 5/2.5 is 2 not 3.

-11 -(-42) A double negative makes a positive

-11 + 42

The cost of renting a car is $46/week plus $0.25/mile traveled during that week. An equation to represent the cost would be y=46
julsineya [31]

The answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The equation to represent the cost would be y=46+0.25x

x is the number of miles.

a) What is your cost if you travel 57 miles?

Plug x = 57 in the above equation:

y = 46 + 0.25(57)

y = $60.25

b) If your cost was $65.00, how many miles were you charged for traveling?

Plug y = 65 in the equation:

65 = 46 + 0.25x

x = 76 miles

c) Suppose you have a maximum of $100 to spend for the car rental. What would be the maximum number of miles you could travel?

Plug y = 100 in the equation:

100 = 46 + 0.25x

x = 216 miles

Thus, the answer for part a is $60.25, for part b the answer is 76 miles, and for part c the answer is 216 miles.
